When pressing respectively while (ON) switch SW 1, SW2, SW3, SW4, closed be connected in series in resistance R 7, R8, the R9 of each switch, the circuit of R10.In the time that release is pressed, switch SW 1, SW2, SW3, SW4 disconnect the circuit with the resistance R 7 that is connected in series in each switch, R8, R9, R10.Thereby, there is no under the state of push switch SW1, SW2, SW3, SW4 the circuit of a closed resistance R6.
The combination of the ON state by switch SW 1~SW4, the input voltage of the microcomputer 29 based on being built in the resistance R 4 of circuit of main body of dust collector 5 sides and the dividing potential drop of R6 (when switch SW 1~SW4 is all OFF) or R6 and R7, R8, the parallel resistance of R9, R10 and the dividing potential drop of R4 (any of switch SW 1~SW4 for ON time) changes.Microcomputer 29 judges operation mode according to this input voltage, carries out to the control of supply electric power and the motor 19 of electric blowing machine 9 according to the ON state of the switch SW 1~SW4 of console switch 8.
The 31st, dust suction state detection sensor portion, possesses dust suction state detection sensor 32.The each resistance that is connected in console switch 8 is connected in parallel with the resistance R 5 that is connected in dust suction state detection sensor 32, is connected with microcomputer 29 with the negative terminal of the comparator C P that is located at main body of dust collector 5 sides.The output of overlap operation switch 8 and the output of dust suction state detection sensor 32 in 1 wiring in flexible pipe 4, and be connected to the negative terminal of comparator C P.Dust suction state detection unit 33 is the circuit that the signal voltage of the overlapping output of console switch 8 and the output of dust suction state detection sensor 32 are only made as to the output of dust suction state detection sensor 32.R1 is pull-up resistor, and R2, R3 are the divider resistances that forms the reference voltage of comparator C P.
Figure 12 is the figure of the production method of the detection signal of explanation dust suction state detection sensor 32.
In the time that two electrodes 37,38 of dust suction state detection sensor 32 connect via movable brace 40, the resistance R 5 that is connected in series in dust suction state detection sensor 32 is connected in parallel with the parallel resistance of console switch 8 sides.Then, DC voltage constant voltage power supply 28 being provided by these combined resistance in parallel and the resistance R 4 that is located at main body of dust collector 5 sides carries out the voltage of dividing potential drop, is provided to comparator C P and microcomputer 29.
On the other hand, when the movable brace 40 of dust suction state detection sensor 32 not with two electrodes 37,38 at least one electrode contact time, cut off the conducting of 37,38, two electrodes, the circuit of off resistance R5.Its result, DC voltage constant voltage power supply 28 being provided by parallel resistance and the resistance R 4 that is located at main body of dust collector 5 sides of console switch 8 sides carries out the voltage of dividing potential drop, is provided to comparator C P and microcomputer 29.This voltage from movable brace 40 conductings the voltage between two electrodes 37,38 time different.
Then, action is described.
In the time using electric vacuum cleaner 100, to connect dust collecting part connector 15 and dust collecting part inflow entrance 21, and connect the mode of main body inflow entrance 17 and dust collecting part flow export 22, by dust collecting part 20 be positioned in main body cover 10 above, by dust collecting part fixed part 23 and dust collecting part fixing hole 18, dust collecting part 20 is fixed to main body cover 10.Then, in the time that operating operation switch 8 drives the electric blowing machine 9 being housed in main body cover 10, the dust laden air being attracted by the attraction of electric blowing machine 9 is invaded in main catheter body 14 through flexible pipe connector 13, enters into dust collecting part 20 through dust collecting part connector 15 and dust collecting part inflow entrance 21.Be included in the airborne dust that enters into dust collecting part 20 and become trapped in dust collecting part 20.Trap dust air afterwards by dust collecting part 20, invaded in main body cover 10 by dust collecting part flow export 22 and main body inflow entrance 17, by No. 41 and 2 filters 42 of No. 1 filter.Now, be included in airborne fine dust and become trapped in No. 41 and 2 filters 42 of No. 1 filter.The air that has passed through No. 41 and 2 filters 42 of No. 1 filter arrives electric blowing machine 9, and then passes through not shown internal path from steam vent 16 exhausts.In dust collecting part 20, residual dust in the situation that, take off dust collecting part 20 from main body cover 10 and abandon residual dust.
In hand hose line 3 and dust suction state detection sensor 32, become the movable brace 40 with electric conductivity across the state of opposed electrode 37,38, only otherwise apply from outside vibration and just form the circuit that electricity is closed.In the time being applied to dust suction state detection sensor 32 from outside vibration, movable brace 40 from the some of electrode 37,38 or two free, moment disconnecting circuit, but can contact the state of repeat circuit closure across electrode 37,38 at once.
In addition, at the hand hose line 3 that is provided with dust suction state detection sensor 32 owing to following the variation of the seesawing of dust suction action, dust suction posture causes changing with respect to the gradient on ground, movable brace 40 is because the quality of self is carried out along the circular-arc inertia motion of electrode side surface part 37a, 38a, and movable brace 40 and electrode 37,38 continue to keep and hand hose line 3 does not carry out the position relationship that the situation of motion is as described above identical.
On the other hand, dust suction action is interrupted, for example hand hose line 3 and elongate catheter 2 are erected to desk, wall or electric vacuum cleaner 100 etc., the moving movement of following thus dust suction action disappears and in hand hose line 3 in static state, movable brace 40 and electrode 37,38 form closed circuit or become dead circuit, maintain its state.For example, if static with the state of Fig. 8 (a), circuit maintains closed state.In addition, as shown in Fig. 8 (b), if with static around the such state of Z axis 90-degree rotation, movable brace 40 does not contact with electrode 38, and circuit maintains the state of disconnection.
In the time interrupting dust suction action, if electric vacuum cleaner in operating condition, to have driven electric blowing machine 9, brush motor be directly to interrupt under the state of motor 19, the vibration that electric blowing machine 9, motor 19 and the rotating brush in driving produces is delivered to dust suction state detection sensor 32 via ground, desk, wall etc. or via flexible pipe 4, elongate catheter 2 etc. sometimes.In addition, the air-flow that produces and flow near the flexible pipe 4 hand hose line 3 by the electric blowing machine 9 in driving produces vortex in the inside of flexible pipe 4, elongate catheter 2, due to the vibration producing to flexible pipe 4, elongate catheter 2 inwall conflicts, be sometimes delivered to dust suction state detection sensor 32 via flexible pipe 4, elongate catheter 2 etc. in addition.
The vibration that is delivered to dust suction state detection sensor 32 is to transmit via the dust suction state-detection substrate 58 that has carried dust suction state detection sensor 32.Here, as shown in Figure 6, Figure 7, dust suction state-detection substrate 58 is being orthogonal in the opposition side (back side) of face of having carried dust suction state detection sensor 32 in the direction (Z direction) of paper can be slidably and supporting walls 59 butts.In addition, the upper end of dust suction state-detection substrate 58 is used as elastomeric upper pressure and keeps tool 56 to support, and lower end can be slidably in Z direction and the stage portion bottom surface 55a butt that presses down rib 55.
The motion model of this dust suction state-detection substrate 58 is illustrated in Figure 10.Particle with weight m carries out modelling to the dust suction state-detection substrate 58 that comprises dust suction state detection sensor 32.The particle of weight m is supported by the wall of both sides via the elastomer of elastic constant k and the damper of coefficientoffrictionμ, and vibrates in Z direction.The elastomer of elastic constant k represents that the upper pressure that the elastic constant of Z direction is k keeps tool 56.In addition, the damper of coefficientoffrictionμ represents with dust suction state-detection substrate 58 at the supporting walls 59 of Z side's upward sliding and presses down rib 55, and their synthetic coefficient of friction is μ.
Equation of motion in the time that the particle of the weight m of the motion model to Figure 10 applies the vibration as external force F in Z direction, as known, will be made as t the time and carry out mode as follows and show.
Md2Z/dt2=-μ dZ/dt-kZ+F (formula 1)
The left side is the product of the quality m of particle and the 2 rank differential relevant with time t of Z, the 1st, the right is frictional force, the speed (the 1 rank differential relevant with time t of Z) of particle and the product of coefficient of friction, the 2nd, the right is restoring force, the displacement of Z direction and the product of elastic constant from the equalization point of particle, the 3rd, the right is the external force that represents vibration, is the periodic power changing with sinusoidal manner.
Formula 1 is summed up as following differential equation.
D 2z/dt 2+ 2bdZ/dt+ (ω 0) 2z=F0cos (pt) (formula 2)
Here,
2b=μ/m (formula 3)
(ω 0) 2=k/m (formula 4)
F=mF0cos (pt) (formula 5)
As shown in Equation 5, suppose the vibration of external force F for changing with the sinusoidal manner of angular frequency p (2 π of the frequency of external force F doubly).
The solution of formula 2 is as follows.
Z=Aexp (bt) cos (ω t+ α)+Bcos (pt-β) (formula 6)
Here,
ω 2=(ω 0) 2-b 2(formula 7)
B = F 0 / ( ( ω 0 ) 2 - p 2 ) 2 + ( 2 bp ) 2 (formula 8)
Tan (β)=2bp/ ((ω 0) 2-p 2) (formula 9)
The exp that the right of formula 6 is the 1st represents that e is the exponential function at the end.
The 1st, the right of formula 6 is the general solution while thering is no external force F, represents the intrinsic vibration (or free vibration) of the motion model of Figure 10.Its angular frequency is ω, in 7, shows like that, is determined by m, k, μ.The 2nd, the right of formula 6 is the special solution of external force F, represents the forced vibration of vibrating with the angular frequency p identical with external force.The intrinsic vibration that the right is the 1st, no matter the primary condition of motion is what is all decayed in the mode of exponential function in time, is therefore only left the 2nd when through time of certain degree.The decay of the intrinsic vibration that this right is the 1st is to result from coefficientoffrictionμ according to formula 3.
Due to coefficientoffrictionμ, hour b is little, so the amplitude B of the forced vibration of formula 8 is created near the what is called resonance of the increase (greatly) of p=ω 0.Along with b becomes large, the very big degree (acutance of resonance) of its resonance declines.In addition, in the case of the angular frequency p of external force F is also large than ω 0, according to formula 8, square decay inversely of the amplitude B of forced vibration and p.On the other hand, as described later, in order to suppress not follow the detection of vibration of the action in dust suction, wish to reduce coefficientoffrictionμ, in this case, the b of formula 3 diminishes.Thus, in the case of the angular frequency p of external force F is also less than ω 0, according to formula 8, the amplitude B of forced vibration can be approximately F0/ ω 0 2, do not rely on the value of p, roughly become steady state value.Thereby, in order to suppress not follow the detection of vibration of the action in dust suction, wish the value of ω 0 is diminished.
Here, the vibration of following the action in dust suction is to produce by the motion of the fore-and-aft direction of user's hand hose line 3 (Z direction), and the cycle (the reciprocal required time of the fore-and-aft direction of hand hose line 3) of this vibration is thought approximately 1 second~about several seconds.Thereby the angular frequency of following the vibration of the action in dust suction is 0~6[rad] left and right.On the other hand, electric blowing machine 9 in dust suction interrupt procedure, rotating brush, rotating brush drive minimumly in the frequency of motor 19 of use thinks the vibration that produces by the rotation of rotating brush.In the time that this rotary speed is made as to 10 revolutions per seconds, the angular frequency of the vibration of the rotation of the accompanying rotation brush in dust suction action interrupt procedure is 60[rad] left and right.Thereby, in order to suppress the detection of the vibration in dust suction action interrupt procedure, wish the value of ω 0 to be chosen as also less than 60.For this reason, as shown in Equation 4, need to reduce elastic constant k or strengthen quality m.Requiring in light-weighted electric vacuum cleaner, do not wish to strengthen quality m, and wish to reduce to keep as elastomeric upper pressure the elastic constant of tool 56.
If by screw clamp, the bonding framework that is secured to hand hose line 3, the elastomer that supports dust suction state-detection substrate 58 becomes the framework of hand hose line 3 itself by dust suction state-detection substrate 58.The elastic constant of the framework of hand hose line 3 is significantly greater than the elastic constant that keeps the carbamate of tool 56 as upper pressure, and the value of ω 0 is also that the former is also larger than the latter.Thereby than the framework that dust suction state-detection substrate 58 is fixed to hand hose line 3, while keeping tool 56 to support by upper pressure, the amplitude B of the forced vibration that high-frequency external force causes diminishes.In other words, kept tool to absorb as the vibration in the dust suction action interrupt procedure of high-frequency external force by upper pressure, be difficult to be delivered to dust suction state-detection substrate 58 and dust suction state detection sensor 32.Its result, can suppress the detection of the vibration of not following the action in dust suction.
In dust suction action, in the hand hose line 3 of user's operation, the reciprocating motion that produces fore-and-aft direction (Z direction), the reciprocal required time (cycle) of the fore-and-aft direction of hand hose line 3 is approximately 1 second~about several seconds.Dust suction state detection sensor 32 detects the vibration that this reciprocating motion causes, and exports the signal such to the voltage change of microcomputer 29 via dust suction state detection sensor portion 31.The microcomputer 29 that has received this signal is judged as current in dust suction action, electric blowing machine 9 and motor 19 is carried out to the control of the action of being set by console switch 8.
Then, if directly interrupt dust suction action in the case of the driving of electric blowing machine 9 and motor 19 continues, the vibration that suppresses to be delivered to hand hose line 3 is delivered to dust suction state-detection substrate 58 and dust suction state detection sensor 32, and the movable brace 40 in dust suction state detection sensor 32 is static in motion space 64.Thus, there is no the signal of the voltage of level variation to microcomputer 29 outputs via dust suction state detection sensor portion 31.The microcomputer 29 that has received this signal is judged as current dust suction and moves in interrupt procedure, and electric blowing machine 9 and motor 19 are controlled to make to reduce to be provided electric power or stop.
In addition, dust suction action is judged as in interrupt procedure, and electric blowing machine 9 and motor 19 are controlled and made to reduce when electric power being provided or stopping, if again start dust suction action, in the operated hand hose line 3 of user, the reciprocating motion that again produces fore-and-aft direction (Z direction).Dust suction state detection sensor 32 detects the vibration that this reciprocating motion causes, and exports the signal such to the voltage change of microcomputer 29 via dust suction state detection sensor portion 31.The microcomputer 29 that has received this signal is judged as dust suction action and restarts, and electric blowing machine 9 and motor 19 is carried out to the control of the action of being set by console switch 8.
In the electric vacuum cleaner forming like this, dust suction state detection sensor portion is supported in the framework of hand hose line via elastomer, and described in described elastomeric Elastic ratio, the elastic constant of the framework of hand hose line is also little, therefore can suppress the detection of the vibration in dust suction action interrupt procedure, the vibration in this dust suction action interrupt procedure is the also vibration of high frequency of vibration in the hand hose line while moving than dust suction.
In addition, in dust suction state detection sensor, have according to the movable body of the moving direction displacement of the hand hose line in the dust suction action of electric vacuum cleaner, therefore can be with the vibration of simple structure detection dust suction state detection sensor.
In addition, owing to being provided with damper unit in hand hose line, described damper unit suppresses the motion of the dust suction state detection sensor portion of the motion of the hand hose line in the dust suction action based on electric vacuum cleaner, therefore not the intrinsic vibration meeting decay of detected object, can detect efficiently the motion for the dust suction state detection sensor portion of the vibration as external force as detected object.
In addition, dust suction state detection sensor portion is by supported on both sides, one side can be slidably supported with the guiding wall that is located at hand hose line inwall, opposite side is supported by elastomer, dust suction state detection sensor has across the opposed electrode in gap, and there is the movable brace of electric conductivity, this movable brace can slide with this electrode or can in the motion space being formed by electrode and the continuous electrode side surface part of electrode perimeter, rotate, electrode vertical and with the orthogonal direction of the moving direction of hand hose line in the dust suction action of electric vacuum cleaner on opposite, described motion space forms described electrode is made as respectively to roughly cylindric that bottom surface and diametric(al) above also grow than short transverse, therefore can detect with simple structure the vibration of dust suction state detection sensor.
Figure 13 is the pre-stored tabular value in microcomputer 29 (memory cell) for judged whether to supress console switch 8 by microcomputer 29.According to this tabular value, judge whether to supress which switch of SW1~SW4.That is, carry out the content of operation of decision operation switch 8 by this tabular value, judge dust suction state according to the signal of dust suction state detection sensor portion 31.And whether flexible pipe 4 is connected in the judgement of main body of dust collector 5, also judges according to this tabular value.
The waveform voltage signal that Figure 14 is the A point shown in Figure 11, B is ordered, represents that flexible pipe 4 is connected in the state that main body of dust collector 5, console switch 8 are not pressed.The waveform voltage signal that A is ordered is the signal voltage of console switch 8 and the overlapping waveform of signal voltage of dust suction state detection sensor 32.
When dust suction state detection sensor 32 is repeatedly when ON, OFF state, the signal voltage of output 1.01V~1.53V.Its output waveform outputs to dust suction state detection unit 33.Dust suction state detection unit 33 is take the ON of comparator C P, OFF decision threshold (1.25V) as benchmark, the voltage waveform of being ordered by comparator C P output B.This ON, OFF decision threshold are the voltage that by R2 and R3, the DC voltage of constant voltage power supply 28 is carried out dividing potential drop.In the time having produced than the high voltage of the ON of comparator CP, OFF decision threshold (1.25V), the output of comparator C P becomes 0V, in the time having produced than the low voltage of the ON of comparator CP, OFF decision threshold (1.25V), the output of comparator C P becomes 5V.
Like this, the signal voltage of the signal voltage of overlap operation switch 8 and dust suction state detection sensor 32, from hand hose line 3 to main body of dust collector 5 side transmitted signals, therefore holding wire can be 2.That is, 1 is the holding wire of common potential, is the line that is connected to resistance side module, console switch 8 Figure 11, flexible pipe 4+ hand hose line 3.Another 1 is the line that is connected to switch SW 1~SW4 side of console switch 8, overlapped signal voltage on this line.Thereby, can reduce by 1 holding wire, obtain cheap electric vacuum cleaner.
Figure 15 is the figure of the detection method of the signal voltage of explanation dust suction state detection sensor portion 31.
The detection method of signal voltage (pulse) is described.
Microcomputer 29 (control module) makes variable increment carry out number of pulses to count in the time detecting the trailing edge of signal voltage, and every 100ms (stipulated time) determines signal voltage (pulse) number.Carry out dust suction and move the judgement having or not for certain setting (the 2nd a reference value) is above or be less than setting (the 1st a reference value) according to signal voltage (pulse) number.Then move the condition judgement benchmark that has or not meets more than certain stipulated number (the 3rd a reference value, the 4th a reference value) continuously in these dust suctions, be judged as dust suction action in interrupt procedure or the dust suction action being judged as in interrupt procedure restarts, and change the control of the motor 19 of electric blowing machine 9, inhaler 1.
The 1st a reference value and the 2nd a reference value are set respectively, and these a reference values are stored in microcomputer 29 (memory cell), wherein, during the 1st a reference value is in electric blowing machine 9 drives and the motor of inhaler 1 19 drives, being judged as dust suction action by microcomputer 29 (control module) interrupts, reduce or stop the value of the driving of the motor 19 of electric blowing machine 9 and inhaler 1, the 2nd a reference value is to be judged as the dust suction action being judged as in interrupt procedure to restart, and return to the value that reduces or stop the state before the driving of motor 19 of electric blowing machine 9 and inhaler 1.
About the condition of judging that dust suction is moved in interrupt procedure, for example, set as follows.
The threshold value (the 1st a reference value) of signal voltage (pulse) number X is set as to 11.X < 11 (condition 1)
The threshold value (the 3rd a reference value) that decision condition is met continuously to number of times Y is set as 15.Y >=15 (condition 2)
, this condition is in every 100ms (stipulated time), to become to be less than when 11 number of times meets 15 times continuously at signal voltage (pulse) number to be judged as in action interrupt procedure.
Move about dust suction the judgement restarting, for example, set as follows.
The threshold value (the 2nd a reference value) of signal voltage (pulse) number X is set as to 2.X >=2 (condition 3)
The threshold value (the 4th a reference value) that decision condition is met continuously to number of times Y is set as 4.Y >=4 (condition 4)
, this condition is to count when the number of times becoming in every 100ms (stipulated time) more than 2 meets 4 times continuously and judge that the dust suction action being judged as in interrupt procedure restarts at signal voltage (pulse).
In addition, the 3rd a reference value and the 4th a reference value are also stored in microcomputer 29 (memory cell).
Like this, the 1st a reference value (=11) is set also larger than the 2nd a reference value (=2).In addition, the 3rd a reference value (=15) is set also larger than the 4th a reference value (=4).Thereby, can suppress the judgement in dust suction action interrupt procedure that the error detection of dust suction state detection sensor portion causes, to move the judgment standard that dust suction restarts not tight in dust suction from interrupt procedure in addition, therefore can restart immediately dust suction action, obtain the good electric vacuum cleaner of ease of use.
Then, utilize flow chart that the action of control module is described.
Figure 16 is the flow chart that is described as follows control: in electric blowing machine 9 drives and in motor 19 drivings of inhaler 1, be judged as dust suction action by microcomputer 29 (control module) and interrupt, and reduce or stop the driving of the motor 19 of electric blowing machine 9 and inhaler 1.
In the time making SW2 be ON (S1), start ECO and turn round by force (S2), the motor 19 of inhaler 1 turn round (S3).And the unsettled electric blowing machine 9 of action while beginning in order not make dust suction state detection sensor 32 detect running, the vibration of motor 19, start dust suction state detection sensor and do not detect timer (S4).In S5, do not detect the judgement whether timing of timer finishes.This timing time (not detection time) is 10 seconds.In the situation that not finishing, till proceeding to the timing that does not detect timer and finishing.In the situation that having passed through not detection time, enter S6, make dust suction state detection sensor not detect timer and make zero.
After the processing of S6, enter S7, start comparator output signal counting and process (detection of trailing edge).Then enter S8, start the measurement of 100ms (stipulated time).Then enter S9, judge the process of 100ms (stipulated time).Enter afterwards S10 through 100ms (stipulated time), count value X and the 1st a reference value of the comparator output signal producing in 100ms (stipulated time) are compared to processing.Then enter S11, to satisfying condition continuously in S10,1 number of times Y and the 2nd a reference value compare processing.The in the situation that of being judged to be to have met condition 2 in S11, enter S12.In S12, whether change to the judgement of ECO power decline process.ECO power decline process refers to following control: be judged as dust suction and move in interrupt procedure, the output of electric blowing machine 9 is reduced to without exception 100W by the setting that does not rely on console switch 8.In the situation that not changing to ECO power decline process, enter S8.In the situation that having changed, carry out ECO power decline process and change processing (S13), make output change to 100W (S14), stop the rotation of motor.
Figure 17 is the flow chart that is described as follows control: be judged as the dust suction action being judged as in interrupt procedure and restart, return to and reduce or stop the state before the driving of motor 19 of electric blowing machine 9 and inhaler 1.
Move in interrupt procedure when being judged as dust suction, in the time reducing or stop the state (S16~S18) of driving of the motor 19 of electric blowing machine 9 and inhaler 1, change the control of electric blowing machine 9 or motor 19.Then,, in order not make dust suction state detection sensor 32 detect the vibration of the unsettled electric blowing machine 9 of action, motor 19 after just having changed control, start dust suction state detection sensor and do not detect timer (S19).In S20, do not detect the judgement whether timing of timer finishes.This timing time (not detection time) is 10 seconds.In the situation that not finishing, till proceeding to the timing that does not detect timer and finishing.In the situation that having passed through not detection time, enter S21, make dust suction state detection sensor not detect timer and make zero.
After the processing of S21, enter S22, start comparator output signal counting and process (detection of trailing edge).Then enter S23, start the measurement of 100ms (stipulated time).Then enter S24, judge the process of 100ms (stipulated time).Enter afterwards S25 through 100ms (stipulated time), count value X and the 3rd a reference value of the comparator output signal producing in 100ms (stipulated time) are compared to processing.Then enter S26, to satisfying condition continuously in S25,3 number of times Y and the 4th a reference value compare processing.In S26, satisfy condition 4 in the situation that being judged as, enter S27.In S27, whether change to the judgement of the strong process of ECO.The strong process of ECO is following control: be judged as the dust suction action being judged as in interrupt procedure and restart, the output of electric blowing machine 9 is returned to the state before reduction.In the situation that not changing to the strong process of ECO, enter S23.In the situation that having changed, carry out the strong process of ECO and change processing (S28), change output (S29), start the rotation of motor.
In the electric vacuum cleaner forming like this, the console switch signal of exporting and the signal that the dust suction state detection sensor portion of the motion of detection hand hose line exports of the driving condition that switches electric blowing machine are carried out overlapping, export to the control module of controlling electric blowing machine and motor, and be provided with the dust suction state detection unit that separates the signal that dust suction state detection sensor portion exports the signal overlapping from this on vacuum cleaner main side, and storage judges the memory cell of a reference value of dust suction state and the content of operation of console switch according to the signal of dust suction state detection sensor portion, therefore reduce the quantity of a holding wire and simple in structure, therefore cost is low and be difficult for fault.
In addition, storage: in the driving of electric blowing machine and in the Motor Drive of inhaler, according to the output signal voltage of dust suction state detection sensor portion, the dust suction that is judged as electric vacuum cleaner is moved in interrupt procedure, reduces or stop the 1st a reference value of the output of the motor of electric blowing machine and inhaler; And the 2nd a reference value restarting is moved in the judgement dust suction that is judged as the described electric vacuum cleaner in interrupt procedure, therefore can carry out the setting of the fiducial time of following judgement: extend the interruption of dust suction action judgement fiducial time and shorten dust suction action the judgement restarting fiducial time or shorten the interruption of dust suction action judgement fiducial time and extend fiducial time etc. of the judgement restarting of dust suction action, ease of use is good.
In addition, the umber of pulse of per stipulated time of the signal voltage that control module is exported according to dust suction state detection sensor portion detects the motion of hand hose line, relatively umber of pulse and the 1st a reference value, the situation that is less than the 1st a reference value in umber of pulse judges and moves in interrupt procedure into the dust suction of electric vacuum cleaner, and, relatively umber of pulse and the 2nd a reference value, be that the 2nd more than a reference value situation judges and restarts for the dust suction action that is judged as the electric vacuum cleaner in interrupt procedure in umber of pulse, the 1st a reference value is set greatlyr than the 2nd a reference value, therefore can suppress the judgement in dust suction action interrupt procedure that the error detection of dust suction state detection sensor portion causes, to move the judgment standard that dust suction restarts not tight in dust suction from interrupt procedure in addition, therefore can restart immediately dust suction action, ease of use is good.
In addition, control module compares umber of pulse and the 1st a reference value within each stipulated time, the number of times that is less than the 1st a reference value in umber of pulse is that the 3rd more than a reference value situation judges and moves in interrupt procedure into the dust suction of electric vacuum cleaner continuously, and, within each stipulated time, compare umber of pulse and the 2nd a reference value, becoming the 2nd more than a reference value number of times in umber of pulse is that the 4th more than a reference value situation judges and restarts for the dust suction action that is judged as the electric vacuum cleaner in interrupt procedure continuously, the 3rd a reference value is set greatlyr than the 4th a reference value, therefore can further suppress the judgement in dust suction action interrupt procedure that the error detection of dust suction state detection sensor portion causes, to move the judgment standard that dust suction restarts not tight in dust suction from interrupt procedure in addition, therefore can restart immediately dust suction action, ease of use is good.
In addition, control module is after changing the control of electric blowing machine or motor, while comparing umber of pulse and the 1st a reference value for the first time or while comparing umber of pulse and the 2nd a reference value for the first time, at the counting that starts umber of pulse after official hour, therefore when electric blowing machine and or the action of brush motor can not detect vibration when unstable, dust suction operating state therefore can correctly judge.
Embodiment 2.
In embodiment 1, the 1st a reference value, the 2nd a reference value, the 3rd a reference value and the 4th a reference value store respectively one in microcomputer 29 (memory cell), but in embodiment 2, are the structures that can change these a reference values.
Figure 18 is the figure that a reference value changing unit of the 1st a reference value, the 2nd a reference value, the 3rd a reference value and the 4th a reference value is changed in explanation.
In microcomputer 29, the pre-stored multiple combinations that have the 1st a reference value, the 2nd a reference value, the 3rd a reference value and the 4th a reference value in memory cell 29a.Memory cell 29a is made up of ROM.And the 1st a reference value, the 2nd a reference value, the 3rd a reference value and the 4th a reference value that use in the time using electric vacuum cleaner 100 are stored in memory cell 29b.Memory cell 29b is made up of RAM.In a reference value changing unit 29c, input the signal voltage (with reference to Figure 11) that the A in the module of main body of dust collector 5 is ordered, store memory cell 29b according to this signal voltage into by one in the multiple combinations that are stored in memory cell 29a.
In the time that the power line of electric vacuum cleaner 100 7 is connected to commercial ac power source 24, in the console switch 8 of Figure 11, any switch (SW1~SW4) is not a reference value changing unit 29c that voltage that the A of the state of ON is ordered is input to microcomputer 29.The voltage that A is in this case ordered is the voltage that by the resistance R 6 of console switch 8 and the resistance R 4 of main body of dust collector 5, the DC voltage of constant voltage power supply 28 is carried out dividing potential drop.According to this input voltage, a reference value changing unit 29c, from being stored in the combination of a reference value memory cell 29a, stores a reference value data of standard combination into memory cell 29b.So, in electric vacuum cleaner 200 course of action, judge in the interrupt procedure of dust suction action with the combination that is stored in a reference value in memory cell 29b or the restarting of dust suction action.
According to user's hobby, the combination that is stored in a reference value in memory cell 29b is changed in the situation that is stored in other combination in memory cell 29a, in the time that the power line of electric vacuum cleaner 100 7 is connected to commercial ac power source 24, any switch (SW1~SW4) that makes console switch 8 is ON while power line 7 is connected to commercial ac power source 24.Thus, with the voltage that is connected in series in the resistance of resistance R 7~R10 of switch of ON and the resistance R 4 of the combined resistance in parallel of resistance R 6 and main body of dust collector 5 DC voltage of constant voltage power supply 28 is carried out dividing potential drop, be input to a reference value changing unit 20c.This voltage and any switch (SW1~SW4) are not that the voltage of state of ON is different.According to this input voltage, a reference value changing unit 29c, from being stored in the combination of a reference value memory cell 29a, stores a reference value data of one group of combination into memory cell 29b.Because console switch has four, the voltage that is therefore input to a reference value changing unit 29c is also four different voltages, therefore can from be stored in the combination of four a reference values memory cell 29a, select.Then,, in electric vacuum cleaner 200 course of action, judge in the interrupt procedure of dust suction action with the combination that is stored in a reference value in memory cell 29b or the restarting of dust suction action.Like this, can change the 1st a reference value, the 2nd a reference value, the 3rd a reference value and the 4th a reference value.
In addition, form memory cell 29b by RAM, in the time that power line 7 is connected to commercial ac power source 24, upgraded the data of memory cell 29b according to the input voltage of a reference value changing unit 29c, but also can form memory cell 29b by EPROM.By being made up of EPROM, in the time that power line 7 is connected to commercial ac power source 24, not needing to make any switch of console switch 8 is ON, and ease of use is good.
Like this, possess the 1st a reference value changing unit that changes the 1st a reference value and the 2nd a reference value, therefore can adjust the fiducial time of the judgement of the interruption of the dust suction action corresponding with user's hobby, ease of use is good.
And, possess the 2nd a reference value changing unit that changes the 3rd a reference value and the 4th a reference value, therefore can adjust the fiducial time of the judgement restarting of the dust suction action corresponding with user's hobby, ease of use is good.
